Nthawi yomaliza kuphulika kwa jenereta ya okosijeni kunali ku India mu 2021. Mliri woopsawu unachititsa kuti njira zachipatala za m'deralo ziwonongeke, ndipo kuperekedwa kwa majenereta a oxygen cylinder kuti adzipulumutse okha kunyumba kunali kochepa.Tsopano zitasintha ndondomeko ya mliri wa chitetezo cha dziko la China, kutentha kwa majenereta okosijeni "kwakokedwa" ndi zida zamankhwala monga ma oximeter.
01. Kufunika kwa ma concentrators okosijeni pambuyo popewa mliri watulutsidwa
Makina opangira okosijeni apanyumba adapangidwa koyambirira kwa 1970s.Izi zisanachitike, ma silinda a okosijeni othamanga kwambiri kapena makina otsika otsika a okosijeni amadzimadzi amafunikira kuti pakhale chithandizo chamankhwala cha okosijeni kunyumba, chomwe chimafunikira kuyenda pafupipafupi kuchokera kwa ogulitsa kuti athandizire kupereka mpweya wamankhwala kunyumba.
Pofuna kuwongolera ndalama, zopangira mpweya wa okosijeni zidawonekera ku United States, zomwe zidachepetsa kwambiri zotchinga za opanga kuti alowe pamsika, ndipo kupangidwa kwa ma molekyulu m'zaka za m'ma 1950 kunalimbikitsanso kuthekera kwa zotengera mpweya kuti zigwiritsidwe ntchito kunyumba.Mpaka 1985, nyumba yoyamba yosungira mpweya wa okosijeni inatuluka ku United States.
Mliri wapadziko lonse lapansi wa kachilombo ka korona watsopano womwe udayamba mu 2020, makamaka kufalikira kwakukulu ku India, wachulukitsa kufunikira kwapadziko lonse lapansi kwa zotengera mpweya.Nthawi yomweyo, ma oximeter omwe amatha kuyeza kuchuluka kwa okosijeni wamagazi kumayambiriro kwa chithandizo amakopa chidwi.
Nthawi yofikira 2023, ndikumasulidwa kwa kupewa ndi kuwongolera miliri ku China kumapeto kwa 2022, kupewa matenda oopsa komanso kuchiza odwala omwe akudwala kwambiri kwakhala chinthu chofunikira kwambiri.
Pambuyo pa matenda ndi korona watsopano, ngati pali zizindikiro zosautsa monga dyspnea ndi hypoxemia, zimatha kumasulidwa ndi mpweya wa okosijeni, ndipo jenereta ya okosijeni ingathandize odwala omwe ali paokha, monga okalamba omwe ali ndi matenda oyamba.
Zomwe zimagwiritsidwa ntchito zimasonyeza kuti kugwiritsa ntchito mpweya wa okosijeni ndi anthu azaka zapakati ndi okalamba, amayi apakati, odwala apadera, etc., omwe ali ndi mphamvu kuchokera ku 1L-3L mpaka 5L-10L.Anthu omwe ali ndi magawo osiyanasiyana a hypoxia amatha kuyesa kugwiritsa ntchito ma concentrators okosijeni atakambirana ndi dokotala.
Mphamvu yaying'ono ya 1-2L ndi ya mtundu wa chisamaliro chaumoyo (mtundu wapakhomo).Imawongolera momwe thupi limaperekera okosijeni, limachotsa kutopa, ndikubwezeretsanso magwiridwe antchito a thupi kudzera mu oxygen.Ndiwoyenera kwa ena azaka zapakati ndi okalamba, amayi apakati, ndi anthu omwe ali ndi thupi lofooka omwe ali ndi zizindikiro za hypoxia., othamanga, ogwira ntchito zolemetsa komanso ogula maganizo.Kuti mupite ku Qinghai-Tibet Plateau, majenereta a okosijeni amathanso kuchepetsa kukhumudwa komwe kumachitika chifukwa cha kukwera kwambiri.
Malinga ndi Njira Zoyang'anira Kulembetsa ndi Kusunga Zida Zachipatala zoperekedwa ndi Order No. 47 ya State Administration for Market Regulation pa Ogasiti 26, 2021, ndikofunikira kuti zida zachipatala za Class I zilembedwe, ndi 1-2L mphamvu ya okosijeni. ma jenereta ndi a Class I ndipo ayenera kujambulidwa.Zida zamankhwala za Class II, monga zotengera mpweya wa 3L ndi kupitilira apo, ziyenera kufunsira satifiketi yolembetsa.
Voliyumu yayikulu ya 3L ndi pamwambapa ndi kalasi yachipatala, yomwe imathandizira matenda a hypoxic pachimake komanso osapumira, matenda amtima ndi cerebrovascular ndi matenda ena a hypoxic popereka mpweya kwa odwala.Pali ogula osocheretsa pamsika, ndipo 1-2L imatanthauzidwa ngati chipatala cha oxygen concentrator, chomwe chimafuna kuti tikhale otseguka pamene tikugula.
Othandizira okosijeni amtundu wamankhwala ali m'gulu lachiwiri la zida zamankhwala zomwe zili ndi chiopsezo chocheperako zomwe zafotokozedwa mu Malamulo pa kuyang'anira ndi kuyang'anira zida zamankhwala ndipo zimafunikira kuwongolera ndi kasamalidwe kolimba kuti zitsimikizire chitetezo ndi mphamvu zawo, zomwe zili zoyenera kupanga mpweya wowonjezera. mpweya, chithandizo cha okosijeni kapena mpumulo wamavuto obwera chifukwa cha kusowa kwa okosijeni.
The oxygen concentrator ndi chida chothandizira chothandizira chomwe chatchulidwa mu "Mapulani Onse Okwaniritsa "Class B ndi B Tube" ya Novel Coronavirus Infection".
Pakadali pano, majenereta ambiri a okosijeni am'nyumba pamsika ndi ma jenereta a okosijeni a molekyulu, omwe amadziwika ndi mtengo wotsika mtengo, osavuta kugwiritsa ntchito, osunthika, komanso kunyamula motetezeka.
Mfundo yogwirira ntchito ya jenereta ya okosijeni ya sieve ndiukadaulo waukadaulo wa Press Swing adsorption (PSA) ndiukadaulo wa desorption.Pa ntchito, nayitrogeni mu mlengalenga ndi adsorbed ndi otsala mpweya mu mlengalenga amasonkhanitsidwa, amene anayeretsedwa ndi kusandulika kukhala mkulu ndende mpweya, ndiyeno mpweya amaperekedwa kwa odwala mpweya machubu.Njira yonseyi imayendetsedwa nthawi ndi nthawi komanso mwamphamvu, ndipo sieve ya molekyulu siidyedwa.
Ngakhale jenereta ya okosijeni imatchedwa "kupanga okosijeni", sikuti imatulutsa mpweya, koma imagwira ntchito yochotsa, kusefa, kuyeretsa ndi kusonkhanitsa mpweya mumlengalenga.Oxygen concentrators sathandizanso thupi la munthu kuti litenge mpweya, zomwe zimafuna kuti odwala omwe amatenga mpweya azikhala ndi mwayi wopuma.
M'zaka zitatu za mliriwu, takumana ndi kuphulika kwapamphumi komanso kutayika kuchokera ku ma thermometers a pamphumi, ma thermometers mpaka ma oximeters, ma ventilator, majenereta a okosijeni, ndi zina zambiri, kuyambira pakuzindikirika kosavuta kupita ku chithandizo cha adjuvant, ndipo njira zoyankhira zachulukirachulukira. wathunthu.
Poyerekeza ndi chenjezo loyambirira la oximeter, jenereta ya okosijeni imagwira ntchito inayake yoteteza kwa anthu omwe amafunikiradi.Ndi kuchuluka kwachangu kwa anthu omwe ali ndi kachilomboka, zomwe zikuchitika pano zimayesa chidaliro cha anthu pakusowa kwa chithandizo chamankhwala, komanso cholumikizira mpweya wapanyumba kwa okalamba, odwala omwe ali ndi matenda am'mimba, amayi apakati, ndi zina zambiri. .
